The observation of the Sagnac effect for massive material particles offers a significant enhancement in sensitivity when compared to optical interferometers with equal area and angular rotation velocity. For this reason, there have been suggestions to employ solid-state interferometers that rely on semiconductors and graphene. We investigate the Sagnac effect in Dirac materials governed by the relativisticlike quasiparticle dispersion law and show that the fringe shift is still determined by the mass of a free electron. This confirms that graphene is indeed a promising material for creating solid-state Sagnac interferometers. Considering monolayer graphene with its linear dispersion law and comparing it with light provides a deeper understanding of the Sagnac effect.

狄拉克费米子旋转环中的萨尼亚克效应


与具有相同面积和旋转角速度的光学干涉仪相比，对大块材料颗粒的萨格纳克效应的观察显着提高了灵敏度。因此，有人建议采用依赖半导体和石墨烯的固态干涉仪。我们研究了狄拉克材料中受类相对论准粒子色散定律控制的萨尼亚克效应，并表明条纹位移仍然由自由电子的质量决定。这证实石墨烯确实是用于制造固态萨格纳克干涉仪的有前途的材料。考虑单层石墨烯的线性色散定律并将其与光进行比较，可以更深入地了解萨尼亚克效应。
